Abstract: 1309737 Mixing T J KEARNEY 29 June 1970 [5 July 1969 21 April 1970] 33975/69 and 18928/70 Heading B1C [Also in Division C1] A method of dispersing solid or liquid material in a liquid comprises causing a surface portion of liquid containing the material to be dispersed to flow over a weir 13 into a collecting chamber 12, entraining the collected liquid in a stream of liquid, and injecting the stream of liquid including the entrained portion into a body of liquid below the surface thereof. A venturi pump 15 may be used for entrainment and injection. The main stream of liquid flowing through the pump may be supplied from the body of liquid into which the stream is injected by means of a pump (not shown). The body of liquid may be that from which the surface portion is drawn off, as shown; or, it may be in a tank separate from the tank from which the surface portion is drawn off, Fig. 4 (not shown). The method may be carried out in a jacketed vessel provided with a central collection chamber and optionally an internal heater, Fig. 3 (not shown). The surface liquid collected in the chamber may be entrained by liquid recirculated from the bottom of the vessel, or by a fluid from a separate source. The latter may be heated e.g. steam. The method may be used for dispersing paint particles in air-washing liquids from paint spray booths, dispersing foam and oil slicks, and homogenising milk.

Abstract: 1314891 Electrode grids IMPERIAL CHEMICAL INDUSTRIES Ltd 29 Sept 1971 [14 July 1970] 34111/70 Heading H1B [Also in Division C3] An electrode grid for supporting active material in a secondary cell is formed, at least in part, from an electrically conducting resin composition comprising glass fibres coated with a metal which has been applied in a molten state. The grid has special application to lead-acid batteries in which instance the metal coating is of lead. The entire grid may be formed by moulding and stamping techniques from the composition or the composition may be applied as a layer to an existing grid. The resin may be a thermosetting, thermoplastic or rubber material, a preferred resin being polypropylene. In a manufacturing process lead-coated glass fibre is prepared by drawing glass from a spinneret through molten lead and then through molten propylene, the resultant skein being subsequently chopped to a mean length of 2 mm. and mixed, where necessary, with further polypropylene to obtain a composition in which the proportion of lead-coated glass fibre forms 30-60% by weight. The glass fibre is 10-20 microns in diameter with a metal coating <SP>1</SP>/ 40 -4 microns thick. The conductivity of the composition may be improved by the addition of carbon black. The Specification also refers to coating the glass fibres with zinc and aluminium.

Abstract: 1333250 Polyester resin capsules EXCHEM HOLDINGS Ltd 14 Oct 1971 [19 Oct 1970] 49606/70 Heading C3P [Also in Divisions E1 and F2] A resin capsule comprises a frangible longitudinally extending casing having disposed therein an unsaturated polyester resin system substantially in contact with a catalyst component and an activator component, the catalyst and activator components being such that, whilst they are substantially unmixed the catalyst and activator remain substantially inert with respect to the resin system so that there is substantially no formation of gelled or cured resin at any interface with the resin system, on intimate mixing of both the catalyst component and the activator component with the polyester resin system the catalyst is caused to become activated by physical or chemical means with consequent curing of the unsaturated polyester resin. The catalyst and activator components may be disposed as separate entities within the casing, the catalyst being rendered stable with respect to the polyester resin system prior to mixing therewith by having a pH lower than that on which the catalyst will cure the system, and the activator component being a basic material incapable alone of initiating polymerization of the system at ambient temperatures. The catalyst and activator components may be combined to form a substantially anhydrous single entity within the casing, there being a water component present as a separate entity within the casing. In the examples polyester resin systems comprising a polyester prepared from maleic anhydride, phthalic anhydride, propylene glycol and diethylene glycol, hydroquinone, styrene, pyrogenic silica and calcite; catalyst components comprising ammonium persulphate, water, ethylene oxide nonyl phenol condensate, glycerine, calcite, pyrogenic silica, dibutyl phthalate, sodium persulphate, castor oil and dolomite; activator components comprising calcium hydroxide, water, glycerine, calcite and triethanolamine; a catalyst/activator component comprising ammonium persulphate, Portland cement, ethylene oxide nonyl phenol condensate, dibutyl phthalate and calcite and a water component comprising hydroxyethyl cellulose, water and calcite are placed in polyester tubular films. The capsules are placed in drill holes in concrete, or coal face and a block of carboniferous limestone and wooden dowels and mild steel bolts are rotated in the holes to mix the components of the capsules and cement the dowels or bolts in position.

Abstract: 1341742 Drying calcium carbonate ENGLISH CLAYS LOVERING POCHIN & CO Ltd 2 May 1972 [7 May 1971] 13835/71 Heading C1A [Also in Division F4] Wet processed natural calcium carbonate is treated to produce a bulk-handleable material in a method comprising: (a) partially dewatering the wet processed carbonate to obtain a superficially dry particulate material; (b) subjecting the partially dewatered carbonate to mechanical working to express water from the body of the particles, and (c) mixing dry or substantially dry powdered calcium carbonate with the moist material in an amount sufficient to absorb the free surface water liberated from within the particles of partially dewatered carbonate. Preferably the wet processed carbonate is dewatered until it contains 17 to 25% by weight of water, the partially dewatered carbonate is mechanically worked such that there is dissipated therein from I to 90 horsepower hours of energy per ton of dry carbonate, and the substantially dry carbonate contains not more than 29% by weight of water. Preferably the final product has a moisture content of 10 to 16% by weight. The partial dewatering may be carried out in tube pressure filters and the mechanical working in a trough, ribbon, paddle, roller pan or dough mixer. In an example a paddle mixer is used, dry CaCO 3  being added at 3 points before the material passes to a finger crusher after which it is mixed with more dry CaCO 3  in a 2nd paddle mixer.

Title: Tamper evident closure
Inventor: TANSEY CHARLES MARTIN
IPC: B65D41/34
Filed: 1993-07-14
Abstract: The invention provides a mould for use in the injection moulding of a closure (10) from a synthetic plastics material. Such a closure (10) is suitable for a container having an externally screw-threaded neck and comprising a top (15) and a depending skirt (16) which has on its internal surface a screw-thread complementary to the screw-thread on the container. A free edge of the depending skirt is joined by a plurality of frangible bridges (13) to a tamper-evident band (11) which comprises a generally cylindrical body portion and a continuous or segmented rib (18). The rib extends inwardly of the body portion and is adapted to provide a lip to engage under a retaining flange extending outwardly from the neck of the container below the screw-thread thereon. The rib (18) has an upper side facing generally towards the top of the closure and an under side facing generally away from the top. The mould defines the upper side of the rib (18) as comprising a first surface contiguous with the body portion of the band, which surface slopes inwardly and downwardly from the top portion (15), and a second surface which is positioned radially inwardly from the first surface, the second surface having a slope angle more nearly normal to the longitudinal axis of the closure than the first surface is to that longitudinal axis. The mould is capable of being operated at extremely high rates to produce closures with improved resistance to removal from the container. <IMAGE>
